[0058] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0059] In order to solve the existing problem of not being able to effectively optimize the construction period of the foundation pit underground continuous wall joint structure, resulting in low construction efficiency and inability to effectively ensure construction quality, please refer to Figure 1 , this embodiment provides the following technical solutions:

[0060] A method for optimizing the construction period of a foundation pit underground continuous wall joint structure, comprising:

[0061] Collect and pre-process multi-source data of foundation pit underground continuous wall joint structure, and securely store the pre-processed multi-source data of foundation pit underground continuous wall joint structure;

[0062] In this embodiment, multi-source data of the foundation pit underground continuous wall joint structure is collected, including:

[0063] Intelligent data collection equipment is used to monitor in real time the completion time of the joint pipe hoisting and concrete pouring stages, as well as the duration of the excavation, trench cleaning, and concrete curing processes, to obtain construction progress data.

[0064] Intelligent data collection equipment is used to monitor the verticality and flatness of the joint pipe, the strength and density of the concrete, and the anti-leakage performance of the water injection test in real time to obtain quality inspection data;

[0065] Based on the construction progress data and quality inspection data, the multi-source data of the foundation pit underground continuous wall joint structure is determined.

[0066] In this embodiment, preprocessing of multi-source data of the foundation pit underground continuous wall joint structure includes:

[0067] Clean the multi-source data of the foundation pit underground continuous wall joint structure to remove the noise data and reduce the noise interference;

[0068] Check the multi-source data of the foundation pit underground continuous wall joint structure one by one, identify the missing data and abnormal data in the multi-source data of the foundation pit underground continuous wall joint structure, and evaluate the missing data and abnormal data;

[0069] When the missing data and abnormal data are useful for optimizing the construction period of the underground continuous wall joint structure of the foundation pit, the missing data and abnormal data are processed according to the data integrity; when the missing data and abnormal data are useless for optimizing the construction period of the underground continuous wall joint structure of the foundation pit, the missing data and abnormal data are removed.

[0070] Specifically, the data collection frequency of construction progress data and quality inspection data is adjusted based on the removal of missing data and abnormal data, including:

[0071] Extract the number of data items corresponding to the removed missing data and abnormal data;

[0072] The number of data items corresponding to the elimination of the missing data and abnormal data is divided according to the construction progress data and the quality inspection data, and the number of data elimination items corresponding to the construction progress data and the number of data elimination items corresponding to the quality inspection data are obtained;

[0073] Retrieve the total number of data collection items corresponding to the construction progress data and quality inspection data;

[0074] The number of data elimination items corresponding to the construction progress data and the number of data elimination items corresponding to the quality inspection data are respectively ratio-processed with the total number of data collection items corresponding to the construction progress data and the quality inspection data to obtain missing value ratio parameters corresponding to the construction progress data and the quality inspection data;

[0075] Retrieving the data collection sliding time window corresponding to the construction progress data and quality inspection data;

[0076] Retrieve the number of data elimination items that appear in each sliding time window corresponding to the construction progress data and quality inspection data;

[0077] Obtain the standard deviation of the number of data elimination items that appear in all sliding time windows corresponding to the construction progress data and the quality inspection data according to the number of data elimination items that appear in each sliding time window corresponding to the construction progress data and the quality inspection data;

[0078] The data collection frequency of the construction progress data and the quality inspection data is adjusted using the item number standard deviation and the missing value ratio parameters corresponding to the construction progress data and the quality inspection data.

[0079] The technical solution described above achieves the following: first, the number of data items corresponding to missing and abnormal data to be removed is extracted, and the number of data items to be removed for construction progress and quality inspection data is calculated. Next, the total number of data items collected is retrieved and the missing value ratio parameters for both are calculated. The data collection sliding time window and the number of data items to be removed in each window are retrieved and the standard deviation of the number of items is calculated. Finally, the standard deviation of the number of items and the missing value ratio parameters are used to adjust the collection frequency of construction progress and quality inspection data. By calculating the missing value ratio parameters, the percentage of construction progress and quality inspection data removed due to missing or abnormal data is quantified, converting data quality into a calculable value. This provides a clear basis for frequency adjustment, accurately linking frequency adjustment to data quality status and avoiding blind adjustments. The sliding time window and the standard deviation of the number of items are introduced to capture fluctuations in the number of data items to be removed within different time windows. Fluctuations in the number of data items to be removed reflect dynamic changes in data quality, and the standard deviation of the number of items accurately captures the extent of this fluctuation, allowing frequency adjustment to dynamically adapt to fluctuations in data quality, improving timeliness and adaptability. The number of excluded items and missing value ratio parameters are calculated for construction progress and quality inspection data respectively to distinguish the quality status of different data types. Due to the different characteristics and importance of construction progress and quality inspection data, frequency adjustment strategies are adapted to meet the collection requirements of different data types and ensure the targeted and effective data collection. The collection frequency is dynamically adjusted based on data quality (missing data, abnormal conditions). When the data quality is poor (missing data, many abnormal conditions), the frequency can be reasonably increased to supplement valid data; when the data quality is good, the frequency can be reduced to reduce resource consumption. Optimize the allocation of data collection resources, improve data collection efficiency and cost-effectiveness, and ensure that construction data collection is both comprehensive and efficient. Reasonable collection frequency adjustment ensures the timeliness and effectiveness of construction progress and quality inspection data. High-quality, frequency-adapted data provides reliable support for construction management decisions (such as progress control and quality acceptance), reduces decision-making errors caused by data problems, and helps the smooth progress and quality assurance of construction projects. The standard deviation of the number of items reflects the fluctuation in the number of data elimination items. Taking this fluctuation into account when adjusting the frequency can reduce the large fluctuations in the collection frequency caused by fluctuations in data quality, make the collection frequency adjustment more stable, ensure the stability and continuity of data collection, and facilitate the long-term monitoring and analysis of construction data.

[0080] Specifically, the data collection frequency of the construction progress data and the quality inspection data is adjusted using the item number standard deviation and the missing value ratio parameter corresponding to the construction progress data and the quality inspection data, including:

[0081] Retrieve the weight value of the corresponding data to be removed in each sliding time window corresponding to the construction progress data and quality inspection data;

[0082] Obtain the weight standard deviation of the removed data that appears in all sliding time windows corresponding to the construction progress data and the quality inspection data according to the weight value of the removed data that appears in each sliding time window corresponding to the construction progress data and the quality inspection data;

[0083] Normalizing the data weight standard deviation to obtain the normalized data weight standard deviation;

[0084] Extract the standard deviation of the number of items corresponding to the number of data items removed from all sliding time windows corresponding to the construction progress data and quality inspection data;

[0085] Normalizing the standard deviation of the number of items to obtain the normalized standard deviation of the number of items;

[0086] The data collection frequency of the construction progress data and the quality inspection data is adjusted by using the normalized item number standard deviation and the normalized data weight standard deviation in combination with the missing value ratio parameters corresponding to the construction progress data and the quality inspection data.

[0087] The adjusted data collection frequency of construction progress data and quality inspection data is obtained through the following formula:

[0088]

[0089] Where F represents the data collection frequency of construction progress data and quality inspection data after adjustment; F0 represents the data collection frequency of construction progress data and quality inspection data before adjustment; s represents the missing value proportion parameter corresponding to construction progress data and quality inspection data; σ m and σ n They represent the normalized standard deviation of the number of items and the standard deviation of the data weight corresponding to the construction progress data and quality inspection data respectively. -5*(s-0.3) The Sigmoid function transforms the linear variation of the missing value ratio parameter, s, into a nonlinear correction. When s < 0.3 (good data quality), the correction factor approaches 1, resulting in a small frequency adjustment. When s > 0.3 (poor data quality), the correction factor increases rapidly, intensifying the need for frequency adjustment. This aligns with the principle that "poorer data quality requires a higher frequency of supplementation." By normalizing the missing value ratio parameter s, the fluctuation correction term is associated with the basic deterioration degree of data quality, avoiding excessive interference of fluctuation correction in basic quality assessment, and ensuring that frequency adjustment responds to dynamic fluctuations and anchors basic quality requirements. Existing technologies often simply linearly associate data quality with acquisition frequency, ignoring the "marginal effect of data quality deterioration" (such as when the quality is extremely poor, a small improvement in quality requires a larger frequency adjustment). This formula uses the Sigmoid correction factor to achieve a "layered response" to data quality: fine-tuning when the quality is good and strong correction when the quality is poor, accurately matching the "gradual demand for data quality from good to poor" in construction scenarios, and improving the sophistication of frequency adjustment. Traditional methods often focus solely on the mean of data quality, ignoring the impact of quality fluctuations on frequency. This formula combines the standard deviation of the number of items (dynamic elimination of fluctuations) and the standard deviation of the data weight (dynamic weight fluctuations), through Synergistically reflect the comprehensive effects of quality fluctuations; and then through Associate the basic quality (s) so that the frequency adjustment responds to both the "long-term quality trend" and the "short-term fluctuation shock" to ensure the stability and adaptability of construction data collection. Normalize the standard deviation of the number of items and the standard deviation of the data weight to eliminate the dimensional differences of different indicators (such as the standard deviation of the number of items is the fluctuation of counts, and the standard deviation of weights is the fluctuation of proportions), so that σ m and σ n It can directly participate in collaborative calculations. Compared to unnormalized mixed calculations, this avoids adjustment bias caused by dimensional conflicts and improves the formula's adaptability to multi-dimensional construction data. Construction progress and quality inspection data are characterized by the need for timely re-collection of deteriorating quality and dynamic response to fluctuations. This formula adapts to the marginal effects of quality degradation through a Sigmoid factor. Compared to general frequency adjustment models, it more accurately meets the actual needs of construction data collection, reduces frequency inaccuracies caused by model mismatch, and improves the balance between construction data quality and collection efficiency.

[0090] The technical solution described above achieves the following: first, the number of missing and abnormal data items removed from construction progress and quality inspection data is extracted, and the number of items removed for each category is calculated. This is then combined with the total number of items collected to calculate the missing value ratio parameter. The sliding time window, along with the number of items removed and the corresponding data weight values, is retrieved. The standard deviation of the number of items and the standard deviation of the data weight are calculated and normalized. Finally, the normalized standard deviation and missing value ratio parameter are substituted into the formula. Based on the pre-adjustment frequency, the adjusted collection frequency is calculated using a Sigmoid correction factor to reflect the degree of data quality degradation, combined with a fluctuation correction term to synergistically reflect the comprehensive effects of quality fluctuations. The missing value ratio parameter quantifies the baseline state of data quality, while the Sigmoid correction factor implements a tiered response to quality degradation, fine-tuning the frequency when quality is good and drastically correcting it when quality is poor. This ensures that the collection frequency is precisely aligned with data quality, ensuring data collection effectiveness and reducing decision-making data bias caused by quality issues. The integration of the standard deviation of the number of items (reflecting fluctuations in the number of items removed) and the standard deviation of the data weight (reflecting fluctuations in the removed data weight) synergistically captures dynamic fluctuations in data quality. The fluctuation correction term enables frequency adjustment to respond to short-term fluctuations, preventing untimely or excessive data collection caused by quality fluctuations. This ensures the continuity and stability of construction data and facilitates accurate decision-making in construction management. The number of items and standard deviation of data weights are normalized to eliminate dimensional differences, enabling the coordinated participation of multiple data quality indicators in frequency adjustment. This model breaks the limitations of a single indicator and comprehensively considers both static degradation and dynamic fluctuations in data quality, improving the scientific nature of frequency adjustment and adapting to the complex characteristics of construction data. Frequency adjustment is dynamically based on data quality, with frequency increased to supplement valid data when quality is poor and decreased to conserve resources when quality is good. This optimizes the allocation of collection resources, ensuring the comprehensiveness of construction data while avoiding resource waste and improving collection efficiency. Furthermore, a collaborative mechanism reduces large frequency fluctuations, enhancing data collection stability and facilitating long-term monitoring and analysis of construction data. Based on the unique characteristics of construction progress and quality inspection data, a layered approach responds to quality degradation and collaboratively handles dynamic fluctuations, precisely meeting the data collection needs of construction scenarios. Compared to general models, this model reduces frequency inaccuracy, providing high-quality, frequency-adapted data support for construction management, reducing the risk of decision-making errors, and facilitating the smooth progress and quality assurance of construction projects.

For example, after integration, it is found that the integrated multi-source data of the foundation pit underground continuous wall joint structure is A2...A n , B1, B2...B n , then the data A1 is missing, then fill the missing data A1 to A2...A n , B1, B2...B n , making the integrated multi-source data of the foundation pit underground continuous wall joint structure the same as the multi-source data of the foundation pit underground continuous wall joint structure before the integration.

[0109] When the multi-source data of the foundation pit underground continuous wall joint structure does not match the foundation pit underground continuous wall joint structure construction period threshold, the foundation pit underground continuous wall joint structure construction period analysis result is that the foundation pit underground continuous wall joint structure construction period is abnormal.

[0110] Specifically, according to the construction period threshold of the foundation pit underground continuous wall joint structure, the multi-source data of the foundation pit underground continuous wall joint structure are analyzed. The construction period analysis results of the foundation pit underground continuous wall joint structure are shown in Table 1:

[0111] Table 1: Construction period analysis results of foundation pit underground continuous wall joint structure

[0112]

[0113]

[0114] Therefore, according to the construction period threshold of the foundation pit underground continuous wall joint structure, the multi-source data of the foundation pit underground continuous wall joint structure are analyzed to judge the construction period of the foundation pit underground continuous wall joint structure, that is, the construction quality and construction progress, and then determine the construction period analysis results of the foundation pit underground continuous wall joint structure.

[0115] Among them, when the construction quality is abnormal, it is necessary to optimize and control the construction quality. Otherwise, the abnormal construction quality will lead to failure in the acceptance inspection of the underground continuous wall of the foundation pit, which will in turn affect the construction period. Therefore, it is necessary to optimize and control the construction quality, improve the construction quality and speed up the construction progress, which can shorten the construction period.

[0116] Among them, when the construction progress is abnormal, it is necessary to optimize and control the construction progress, otherwise the abnormal construction progress will affect the construction period. Therefore, by optimizing and controlling the construction progress, the construction progress can be accelerated and the construction period can be shortened.

[0117] Formulate a construction period optimization plan for the underground continuous wall joint structure of the foundation pit, simultaneously optimize the construction progress and construction quality of the underground continuous wall joint structure of the foundation pit, and form a closed-loop construction period optimization for the underground continuous wall joint structure of the foundation pit.

[0118] In this embodiment, the construction progress and construction quality of the foundation pit underground continuous wall joint structure are simultaneously optimized, including:

[0119] Find out the reasons for abnormal construction period in time according to the construction period analysis results of the underground continuous wall joint structure of the foundation pit;

[0120] Based on the reasons for the abnormal construction period, a construction period optimization plan for the underground continuous wall joint structure of the foundation pit is formulated, and the construction progress and construction quality of the underground continuous wall joint structure of the foundation pit are simultaneously optimized to simplify the construction process. The construction period of the underground continuous wall joint structure of the foundation pit is optimized while ensuring the construction quality.

[0121] In this embodiment, a closed-loop construction period optimization of the foundation pit underground continuous wall joint structure is formed, including:

[0122] The underground continuous wall joint structure of the foundation pit after the construction period is optimized is monitored in real time, and the construction period of the underground continuous wall joint structure of the foundation pit is adjusted and optimized according to the monitoring feedback, forming a closed-loop construction period optimization of the underground continuous wall joint structure of the foundation pit.

[0123] In summary, according to the construction period threshold of the foundation pit underground continuous wall joint structure, the multi-source data of the foundation pit underground continuous wall joint structure are analyzed, the construction period of the foundation pit underground continuous wall joint structure is judged, the construction period analysis results of the foundation pit underground continuous wall joint structure are determined, and a construction period optimization plan for the foundation pit underground continuous wall joint structure is formulated. The construction progress and construction quality of the foundation pit underground continuous wall joint structure are simultaneously optimized, forming a closed-loop construction period optimization of the foundation pit underground continuous wall joint structure, which can effectively optimize the construction period of the foundation pit underground continuous wall joint structure, improve construction efficiency and effectively ensure construction quality.
